论文摘要
当创建一个自然动态提供有用的计算操作的量子系统时，设计人员可以使用两个关键工具：哈密顿量和系统的初始状态（编码）的（约束）选择。通常，我们修复了设计，并利用Factum后的编码来容忍实验缺陷。在本文中，我们描述了一种重要的见解，该洞察力将编码结合到设计过程中，并带来根本后果。这将完美的状态转移的研究从指定整个系统的哈密顿量的不切实际的情况转变为更现实的情况，即被给予哈密顿量，我们在设计上别无选择，并设计了两个参数的时间控制，以达到完美的转移。
When creating a quantum system whose natural dynamics provide useful computational operations, designers have two key tools at their disposal: the (constrained) choice of both the Hamiltonian and the the initial state of the system (an encoding). Typically, we fix the design, and utilise encodings post factum to tolerate experimental imperfections. In this paper, we describe a vital insight that incorporates encoding into the design process, with radical consequences. This transforms the study of perfect state transfer from the unrealistic scenario of specifying the Hamiltonian of an entire system to the far more realistic situation of being given a Hamiltonian over which we had no choice in the design, and designing time control of just two parameters to still achieve perfect transfer.
